I have not taken the wheels off and I will look closely soon when I go to the storage garage. I own about 55 various rally 2 wheels mostly 15s but I will have to go thru what I have when the snow melts. I know I dont have JA or JK code since those 69 disc wheels are needed for my goat. Like a fool years ago I sold them and put the 15s on (1987) but back then it was what you did! LOL!
1969 Firebird 350 Coupe, Rust free Texas body, formerly brown, now a TA clone with quality spoiler, latching hood and TA wheel; 1969 GTO Convertible Expresso Brown/Parchment(currently painted red). Both numbers matching. My first love was a Cameo White 67 326 Coupe, bought back in 1983, at the age of 17, for $1,200. Been hooked since on PONTIAC! Working on a 67 400 ragtop for customization-Gulf Turquoise/Parchment/400/4 spd! My winter project!
